Description

Technical Field

[0001] The present application relates to the technical field of fissure dilation catheters, and in particular to a visualized endoscopic fissure dilation catheter with a flushing structure. Background Art

[0002] The technology of transurethral prostate balloon dilatation for patients with prostate hyperplasia is relatively mature. Transurethral cylindrical water balloon prostate dilatation is an innovative surgical method for the treatment of benign prostate hyperplasia that is effective, safe, simple, and minimally invasive. It is a surgical method for the treatment of prostate hyperplasia that preserves the original organ. This procedure has the characteristics of convenient operation, minimal trauma, and high safety factor. It is an ideal choice for elderly and weak patients who cannot tolerate resection surgery or are unwilling to remove prostate tissue.

[0003] When the dilation catheter is used, the catheter will be inserted into the tissue, and the prostate will be dilated by manipulating the dilation catheter. However, after use, a large amount of tissue fluid will adhere to the outer wall of the dilation catheter. If it is not cleaned in time, the liquid will dry and solidify, making it more difficult to clean the dilation catheter at a later time. Utility Model Content
